The work, which is composed solely with the note A, starts out as a “normal” piano piece but soon transforms into something that would be impossible for any musician to play.

The original version was realized for 20 channels. The spatial adaptation was realized by Hervé Desjardin who also proposed the concept of making a piece only using one note.
